Why researches don’t find frozen dinosaurs? We often find the rests of mammoths or other mammals but never of dinosaurs and similars.
I wonder if this is due to the location, eg no dinosaur could survive cold climate, or just they are so sparse and the ice so thick that we didn’t found them yet. Maybe the artic wasn’t inhabited at the time? It would be weird, penguins are there now so some must have adapted somehow.

The planet’s polar ice isn’t permanent. [The oldest ice known is 4.6 million years old.](https://polarjournal.ch/en/2024/04/24/new-record-4-6-million-year-old-ice-found-in-antarctica/#:~:text=The%20record%20for%20the%20oldest,from%20before%20the%20ice%20age.) Ice ages come and go, and there have been periods of time when the whole planet was very warm and there was very little ice. Sea levels were very high.
[There were dinosaurs in antarctica,](https://www.bbcearth.com/news/when-dinosaurs-roamed-antarctica) , because the planet was very warm at that time. The continents weren’t exactly where they are now, but it was far enough south that they had large eyes to cope with long months with no sun.

The northern ice cap floats on the ocean. There are a few islands under it, and it is kind of stuck to Greenland and Siberia, but there is mostly water under there. Nuclear submarines patrol there, nothing but another submarine can find them.
